Processing and Properties of Lead-Free KNN-Based Ceramics
In the present work characterization of lead free ceramics based on KNN has been studied. Ceramics with the chemical composition (1-x)(K0.5Na0.5)Nb1-ySbyO3-xBaTiO3 (x=0.02, 0.04; y=0.04, 0.07) were prepared by conventional ceramic processing technology.

Advanced Engineering Materials, EarlyView.A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

Advanced Engineering Materials, EarlyView.PUF/ENB microcapsules were synthesized based on a sequential factorial design and incorporated into an epoxy matrix. Their anticorrosive action, associated with the self‐healing mechanism, demonstrated that the addition of microcapsules to the coating improved anticorrosive performance compared to pure epoxy coatings, particularly when the encapsulate ...

A Thermal Analysis of Lead-Free Ceramics
International Journal of Physics Research and ApplicationsThermal analysis of lead-free ceramics is based on temperature variation leading to theoretical assessment anticipating the normal conductivity and a.c. conductivity of the material. It is also seen that the change in polarization includes electronic and ionic polarization. The effect of temperature on both electronic and ionic polarization is small at
